2019電腦圖學: W14同是腰間盤就你最突出

Week14 課堂重點

主題：計時器(timer)

I 實作

1、下載Freeglut windows檔案解壓縮

打開project的libglut32.a檔

2、鍵入基礎程式碼

3、先下載wav聲音檔

4、加入聲音跟計時器程式碼

#include <GL/glut.h> #include <mmsystem.h>///Now (1) #include <stdio.h>///printf() void display() { glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); glutSolidTeapot( 0.3 ); glutSwapBuffers(); } void timer(int t)///NOW timer!!!! { glutTimerFunc(1000, timer, t+1 );///NOW timer!!!! 起床要播下一個鬧鐘 printf("timer(t) 的 t是 %d\n", t);///順便印一下現在的t是多少 PlaySoundA("fart.wav", NULL, SND_ASYNC);///Now (2) ///NOW timer!!!! } int main(int argc, char**argv) { glutInit(&argc, argv); glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH); glutInitWindowSize(500,500);///變大了 glutCreateWindow("week 14 timer"); glutDisplayFunc(display); glutTimerFunc(3000, timer, 0);///NOW timer!!!! glutMainLoop(); }

5、成果

II 實作

1、加入旋轉的程式如圖

#include <GL/glut.h>
#include <mmsystem.h>///Now (1)
float angle=0;
void display()
{
    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
    glPushMatrix();
        glRotatef(angle, 0,0,1);
        glutSolidTeapot( 0.3 );
    glPopMatrix();
    glutSwapBuffers();
}
void timer(int t)///NOW timer!!!!
{
    /// 1000 ms = 1 sec,  30 ms = 1/33 sec , 33 fps
    glutTimerFunc(30, timer, t+1 );///NOW timer!!!! 起床要播下一個鬧鐘
    angle += 1;
    glutPostRedisplay();///系統重繪畫面
}
int main(int argc, char**argv)
{
    glutInit(&argc, argv);
    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);
    glutInitWindowSize(500,500);///變大了
    glutCreateWindow("week 14 timer");

    glutDisplayFunc(display);
    glutTimerFunc(3000, timer, 0);///NOW timer!!!!

    glutMainLoop();
}

2、成果

3、改成Translate如圖

#include <GL/glut.h>
#include <mmsystem.h>///Now (1)
float angle=0;
float nowX=0;
void display()
{
    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
    glPushMatrix();
        ///glRotatef(angle, 0,0,1);
        glTranslatef(nowX,0,0);
        glutSolidTeapot( 0.3 );
    glPopMatrix();
    glutSwapBuffers();
}
void timer(int t)///NOW timer!!!!
{
    /// 1000 ms = 1 sec,  30 ms = 1/33 sec , 33 fps
    glutTimerFunc(30, timer, t+1 );///NOW timer!!!! 起床要播下一個鬧鐘
    float alpha =(t%33)/33.0;
    nowX=alpha*1+(1-alpha)*-1;

    angle +=1;
    glutPostRedisplay();///系統重繪畫面
}
int main(int argc, char**argv)
{
    glutInit(&argc, argv);
    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);
    glutInitWindowSize(500,500);///變大了
    glutCreateWindow("week 14 timer");

    glutDisplayFunc(display);
    glutTimerFunc(3000, timer, 0);///NOW timer!!!!

    glutMainLoop();
}

4、成果

III 實作

讓data可以在自己的資料夾打開

1、在資料夾用notepade++打開cdp

.是在這個資料夾的意思

2、確認電腦使用者的名字

IV 實作

加上timer & oldangle & newangle讓動作流暢
